I used gotsent. works really quick, like an hr or so. I added the file from gotsent to itunes, and it plays. but for some reason wont sync or stream to my apple tv. says it not recognizable format? please help.

I'd like to use the fastest converter with good quality. I'm also a windows user. thx

I would assume that this re-packages compatible streams into .mp4 files without re-encoding, if possible. This doesn't work on the Apple TV because MKVs using H.264 tend to use High Profile instead of Main Profile, so you have to re-encode the video for it to play. The Xbox 360 and PS3 support H.264's High Profile, so they don't have issues.

I think you nailed it ... a majority (if not all) of the hi-def MKV's in the wild on the internet all have H264 encodes that are not compatible with the ATV and will not sync via itunes (even though they play in quicktime)

Based on the previous posts, I do not think it is going to work. You will need a different encode of the file you have. Given that it is pre-encoded, and the nature of that process, it is currently not possible to convert that to something that will work. You would need the source file and encode that in a compatiable format.
